==Project pages==
===[[Example project title]]===
One sentence, describing what this project is is about.

'''Team members:''' A, B, C

=== [[QKD receiver characterization (Polarization)]] ===

Calibrated polarization-state generator to characterize polarization analysis modules in QKD receivers and rigorously quantify the impact on secure key rates.

'''Team members:''' Elias X. Huber, various AI agents (open to join forces with other humans as well, you can reach me at elias.x.huber[at typical nus sufix]; please note though that I will likely do the experiment at UTown (CREATE Tower), my schedule tends to be a bit inflexible for team-work, and I am a theorist with no lab experience).

=== [[Control and measurement in the bosonic cQED system]] ===
Using the control and measurement methods to characterize dispersively coupled single superconducting caivty and single transmon qubit system, with a through review of theories and experimental techniques behing it.

'''Team members:''' Grace Pang and Seungwon Jin

==Resources==
Some hopefully useful references should go here.
===Recommended literature===
